Equitable Tolling, and What It Requires
Every late claimant believes their own circumstances were exceptional. Equitable tolling exists for the small subset where that is legally true, and the test has two limbs, the first of which is where most applications actually fail.
The rule in short
Equitable tolling suspends a limitation period where the claimant pursued their rights diligently and some extraordinary circumstance prevented timely filing. Both limbs are required. Ordinary difficulty, ignorance of the law, adviser error and administrative delay generally fail, and the doctrine does not apply to periods that are jurisdictional or subject to repose.
Equitable tolling is the answer to a genuine unfairness and the last refuge of a great many claims that were simply left too long. The distinction between the two is diligence, and it is assessed unsympathetically.
The two limbs
Diligence in pursuing the claim. The claimant must show they were actively pursuing their rights throughout the period, not only at the end of it.
An extraordinary circumstance. Something outside the claimant's control that stood in the way of timely filing.
Both are required. Diligence without an obstacle fails, and an obstacle without diligence fails, which is where most applications end.
Causation is implicit. The circumstance has to have prevented the filing rather than merely coexisted with the delay.
The standard is objective. Reasonable diligence rather than the best the particular claimant could manage.
It is assessed on the whole period. A claimant who did nothing for two years and then acted quickly has still not been diligent.
The burden is on the claimant. Once limitation is pleaded, establishing tolling is for the party relying on it, per what a limitation period does.
It is applied sparingly. Courts describe it as reserved for rare circumstances, and the reported outcomes reflect that.
What usually qualifies
Active concealment by the defendant. Conduct hiding the claim is the strongest case, and it overlaps with its own doctrine, per concealment that stops the clock.
Being actively misled about the deadline. Where the defendant or an official body gave incorrect information that was relied on.
A filing prevented by the forum itself. Where a document was submitted in time and mishandled, tolling frequently follows.
Serious incapacity. Which frequently has its own statutory provision covering the same ground more reliably.
A timely filing in the wrong forum. Some systems toll where the claimant pursued the claim diligently in a court that turned out to lack authority.
Extraordinary external events. Disasters and closures that made filing impossible, subject to how long they lasted.
Fraud on the claimant. Deception that prevented the claim being identified or brought.
Nothing about the merits. A strong claim is not a ground for tolling, however unfair the outcome of the limitation point looks.
A statutory scheme's own relief. Where a scheme provides for late applications on stated grounds, that provision usually replaces the general doctrine.
| Circumstance | Usually tolls | Reason |
|---|---|---|
| Concealment by the defendant | Yes | Claim could not be identified |
| Misinformation from the forum | Often | Reliance was reasonable |
| Filing lost by the office | Often | Claimant did everything required |
| Ignorance of the deadline | No | Not extraordinary |
| Adviser's mistake | Rarely | Attributed to the client |
What usually fails
Ignorance of the deadline. Not knowing a period existed is the most common argument and almost never succeeds.
Ignorance of the law generally. The same point, and unrepresented status rarely changes it.
An adviser's error. Generally attributed to the client, per when the adviser missed it.
Ordinary illness or difficulty. Serious personal circumstances that did not actually prevent filing usually fail the causation point.
Waiting for information. A claimant who delayed to gather evidence could usually have filed and investigated afterwards.
Negotiations in progress. Without a written agreement, talks between the parties do not toll anything at all.
Administrative delay elsewhere. Waiting for another body to decide something rarely justifies missing an unrelated deadline.
Discovering the claim was worth more. A reassessment of value is not an extraordinary circumstance.
Most applications fail on the first limb rather than the second. A claimant who did nothing for eighteen months and then met a genuine obstacle has an obstacle and no diligence, and the doctrine requires both.
Where it cannot apply at all
Jurisdictional periods. No equitable doctrine reaches a limit that conditions the forum's authority.
Statutes of repose. Outer limits measured from the act are immune to tolling of any kind.
Periods a statute says are absolute. Where the legislation excludes extension expressly, the exclusion governs.
Some short procedural windows. Certain appeal and application periods are drafted to be inflexible.
Where a statutory scheme has its own relief. The scheme's provision usually displaces general equitable doctrines.
Where the claimant caused the obstacle. Self-inflicted difficulty is not an extraordinary circumstance.
Where filing remained possible. If the claim could have been issued despite the difficulty, causation fails.
Where the delay continued afterwards. Tolling covers the period of the obstacle, not the months after it ended.
Making the argument
Plead it specifically. Dates, obstacles and steps taken, rather than a general assertion that the delay was understandable.
Evidence the diligence. Correspondence, requests for records and instructions to advisers are what establish it.
Establish causation directly. Explain why the circumstance made filing impossible rather than merely difficult.
Address the period after the obstacle. Show that the claim was filed promptly once the barrier was removed.
Deal with the obvious alternative. If a protective filing could have been made, explain why it was not.
Do not overstate. An argument treating an ordinary difficulty as extraordinary weakens whichever parts of it were real.
Explain what was done instead. Where a claimant could not file, showing what they did do during the period supports the diligence limb directly.
Deal with the length of the delay. A short overrun is assessed differently from one measured in years, and the pleading should meet that head on.
Have a fallback. Where possible, argue that the claim was in time in any event, per when a claim accrues.
Expect it to be decided early. Tolling is usually taken as a preliminary issue rather than left to be resolved at a trial.
Assemble the evidence before pleading it. An allegation of extraordinary circumstances made without the supporting material is weaker than not making it at all.
Consider whether the claim is in time anyway. Where accrual is arguable, establishing that removes the need for the doctrine entirely.
Equitable tolling suspends a limitation period where a diligent claimant was prevented from filing by something outside their control, and both parts of that are required.
Diligence is assessed across the whole period rather than at the end of it, which is why most applications fail on that limb before the obstacle is even examined.
The circumstances that qualify are narrow: concealment, being misled about the deadline, a filing mishandled by the forum itself, serious incapacity and events that made filing genuinely impossible.
The arguments that fail are equally predictable: ignorance of the period, an adviser's error, ordinary hardship, waiting for information and negotiations conducted without an agreement.
The doctrine cannot reach jurisdictional limits or statutes of repose at all, which makes checking the category of the period the first step rather than the last.
Points to carry away
- Two limbs: diligence and an extraordinary circumstance.
- Diligence is assessed throughout, not only at the end.
- Ordinary hardship and adviser error usually fail.
- It does not apply to jurisdictional or repose limits.
- It is argued far more often than it succeeds.
Questions readers ask
What does a claimant have to show for equitable tolling?
Two things, and both are required. First, that they pursued their rights diligently throughout the period rather than only once the deadline approached. Second, that some extraordinary circumstance outside their control actually prevented a timely filing. Causation matters: the obstacle has to have made filing impossible rather than simply difficult. Courts describe the doctrine as reserved for rare cases, and most applications fail on the diligence limb before the obstacle is considered at all.
Does not knowing about a deadline ever justify tolling?
Almost never. Ignorance of a limitation period, and ignorance of the law more generally, is the most frequently advanced argument and one of the least successful, and being unrepresented rarely changes the outcome. The reasoning is that periods are published and discoverable, so not knowing about one reflects an absence of diligence rather than an external obstacle. The narrow exception is where somebody with apparent authority actively misinformed the claimant and reliance on that was reasonable.
Can equitable tolling apply to any deadline?
No, and this is worth establishing before the argument is developed. It cannot reach a period that is jurisdictional, because no equitable doctrine can confer authority the legislature withheld, and it cannot reach a statute of repose, which is designed to be immune to every extension. Statutory schemes with their own relief provisions usually displace the general doctrine as well. Checking which category a period falls into takes minutes and can make the entire tolling analysis unnecessary.

More in Pausing and Extending
A Second Request for Time
A repeat request is assessed against the previous one: whether the earlier estimate was realistic, what was done with the time granted, and whether the reason now is genuinely new. Systems that grant first extensions almost automatically become considerably more demanding on the second, and the strongest material is evidence of the work completed since.
Consent Extensions Between the Parties
Many procedural deadlines can be extended by written agreement between the parties, within limits set by the rules. Others were fixed by the forum or by statute and cannot be varied privately, however cooperative everybody is. Distinguishing the two categories before relying on an agreement is the whole of the exercise, and the distinction is usually stated in the rule that created the deadline.
Seeking Relief Once the Period Has Expired
An application made after expiry usually requires the applicant to show that the failure was excusable, that they acted promptly on discovering it, and that the other side is not materially prejudiced. Some deadlines admit no relief at all, so the first question is whether an application is available before it is drafted.
